Method Index

o GetBSplinePCurveData(CATLONG32,CATLONG32,CATLONG32,double*,double*,double*): Retrieves the poles, knots and weights that fully define a non-uniform, rational BSpline curve.
o GetBSplinePCurveInfo(CATLONG32*,CATLONG32*,CATLONG32*,short*,short*,short*): Retrieves overall information related to the BSpline PCurve.

Methods

o GetBSplinePCurveData

public virtual GetBSplinePCurveData(		`iPoles`,
		`iKnots`,
		`iWeights`,
		`oPoles`,
		`oKnots`,
		`oWeights`)

Retrieves the poles, knots and weights that fully define a non-uniform, rational BSpline curve.

Parameters:

iPoles: Set the number of poles expected to be returned in the oPoles argument. The function is expecting iPoles*2*sizeof(double) bytes of memory allocated by the caller in oPoles.
iKnots: Set the number of knots expected to be returned in the pKnots argument. The function is expecting iKnots*sizeof(double) bytes of memory allocated by the caller in oKnots.
iWeights: Inputs the number of weights expected to be returned in the oWeights argument. The function is expecting iWeights*sizeof(double) bytes of memory allocated by the caller in oWeights.
oPoles: Get the poles making up the curve. The memory is pre-allocated by the caller.
oKnots: Get the knots making up the curve. The memory is pre-allocated by the caller.
oWeights: Get the weights per pole when the curve is rational. The memory is pre-allocated by the caller.

o GetBSplinePCurveInfo

public virtual GetBSplinePCurveInfo(		`oOrder`,
		`oNumPoles`,
		`oNumKnots`,
		`oIsRational`,
		`oIsClosed`,
		`oIsPeriodic`)

Retrieves overall information related to the BSpline PCurve.

Parameters:

oOrder: Get the order of the BSpline.
oNumPoles: Get the number of poles.
oNumKnots: Get the number of knots.
oIsRational: Get TRUE if the curve is rational ( a weight is assigned to every pole ), FALSE otherwise.
oIsClosed: Get TRUE if the curve is closed, FALSE otherwise.
oIsPeriodic: Get TRUE if the curve is periodic, FALSE otherwise.
